Randomized study of intensive MOPP-ABVD with or without low-dose total-nodal radiation therapy in the treatment of stages IIB, IIIA2, IIIB, and IV Hodgkin's disease in pediatric patients: a Pediatric Oncology Group study.

Abstract:

Purpose:
To determine whether the addition of low-dose total-nodal irradiation (TNI) in pediatric patients with advanced-stage Hodgkin's disease who have received eight cycles of alternating mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) and doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) will improve the event-free survival (EFS) and overall survival (OS) when compared with patients who have received chemotherapy only.

Patients and Methods:
At diagnosis, 183 children and adolescents with stages IIB, IIIA2, IIIB, and IV Hodgkin's disease were randomized to receive eight cycles of alternating MOPP-ABVD with or without low-dose TNI.

Results:
Of 183 patients, four were rendered ineligible before treatment was initiated. One hundred sixty-one of 179 patients (90%) were in complete remission (CR) at the completion of eight cycles of alternating MOPP-ABVD; 81 were in the chemotherapy-only group and proceeded to observation off therapy, whereas 80 of 161 were to receive combined modality therapy (CMT). Nine of 80 patients randomized at the time of diagnosis to receive CMT did not receive radiation (RT) because of a protocol violation, but were monitored for EFS and OS and included in all analyses. The estimated EFS and OS rates at 5 years for the 179 eligible patients are 79% and 92%, respectively. The actuarial EFS at 5 years was 80% for patients who received CMT and 79% for patients who received MOPP-ABVD only. The OS for the former group is estimated to be 87% and for the latter patients 96%. Age < or = 13 years of age at diagnosis and the attainment of a clinical CR after three cycles of chemotherapy were associated with a statistically significant improved EFS.

Conclusion:
Our results indicate that after the delivery of eight cycles of MOPP-ABVD, the addition of low-dose RT does not improve the estimated EFS or OS in pediatric patients with advanced-stage Hodgkin's disease.
